Lift Cell Lock [LCL]

When a lifting operation fails—for example, due to an overfilled bin—the system can suspend the affected cell for lifting until the issue is resolved.

The lift cell lock state of unlocked cells is not transmitted in the initial download. Therefore, all lift cell locks must be cleared upon receiving a DS segment. Cells that remain locked for lifting will be transmitted during the initial download.

Segment Example

LCL,xpos,ypos,lock_state
LCL,xpos,ypos,BOTH // cell is locked for lifting operations 
LCL,xpos,ypos,CLEAR // cell is no longer locked for lifting operations

Lock States

State	Description
`BOTH`	Cell is locked for lifting operations
`CLEAR`	Cell is no longer locked for lifting operations
`UNKNOWN`	Unknown cell lock state
